This invention while relatin 7 t) Maniivn ENGINE.

Application filed October 23, 1924. Serial No. 745,381.

generally to marine motors is more particularly concerned with the conversion of automotive engines to marine use by application thereto 5 of special devices adapting it to the somewhat dissimilar requirements of such service.

For instance, motors for Ford cars if adapted to marine purposes might be found economical for the propulsion of small types of boats. Accordingly, the improvements herein are described with particular reference to their incorporation in Ford motors.

It is the principal object of the invention to provide means ofinexpensive and simple type, for associating with a Ford motor a water cooling system which shall include a water pump whereby the motor shall be more rapidly cooled and its working capacity increased as necessary for marine uses. Still another object is to mount such a water pump in an accessible position at the front end of a Ford motor and to remount the standard timer so as to afford space for the water pump.

A further object of the invenpeller.

In carrying out these objects means are provided which not only provide for the necessary angularity but also for the absorption of the thrust and the retention of on within the transmission housing with the exclusion of dirt and water therefrom.

These and other objects will appear at greater length in connection with the detailed description of the embodiment illustrated wherein Figure 1 is a view in side elevation show-.

in the accompanying drawings,

ing a Ford type motor having the improvements associated therewith to adapt it for marine purposes.

Figure 2 is a View in front elevation thereof illustrating particularly the mounting of the water pump and distributor, the cap of the distributor being broken away.

l igure is a detail view partly in side elev ation and partly in section of the water pump and distributor and showing particularly the driving connections between these units and the cam shaft.

igure 4: is a fragmentary view partly in plan and partly in horizontal section, showing the universal connection between the propeller shaft and transmission housing.

As the description proceeds it will appear that some features of the invention may be useful in adapting other types of motor than the Ford to marine usage and for that reas self and mot end on the drawings illustrate the engine itvery conventionally although the front rear ends'corre'spond to those of a Ford or. Such a motor as a has at its front a timing gear cover 6 through which extends forwardly a. cam shaft 0 which ordinarily (3211165 directly thereon a timer such as (Z. The cooling of such motor is ordinarily tem mar incr accomplished by a thermo-siphon sysin which no pump is employed. For ine purposes itis believed desirable to ease the capacity of the cooling system incorporating therein a water pump which may take water from'outboard and discharge it into the exhaust after passing through the engine jacket. t in accordance with the present invention to is proposed remount the distributor (Z at one side of the shaft 0 so as to afford space for the water sum) 6 and )ermit both the Jump and distributor to be driven from the shaft 0. To accomplish this by simple and accessible means which may be readily assembled, it is proposed'to provide a bracket 7' which is bolted to the plate '1) by long bolts 9 entering the same bolt holes which are found ins tandard parts. The pump c is mounted at the forward end of the bracket ,f with its rotor connection centered with respect to the frat and and shaft 0. This rotor connection is illused as a rod 6 which enters a sleeve h is pinned thereto as at 71/, this sleeve being fitted onto the end of the cam shaft 0 driven therefrom by a driving pin if.

The end if of the driving pin 77. is of reduced diameter and enters loosely a recess 0 within the shaftc.

The looseness of the fit of the shaft 0 in the sleeve h and of the reduced end 72, of the driving pin in the rece sate

ah g

ss 0 facilitates assembling and compens for any slight angular or linear misnment of the shaft 0' with the shaft 6. intake pipe 6 is provided at one side of water and dirt therefrom.

the gear pump 6 while the outlet side is connected through a hose (2 with the jacket of the motor, the circulatory system of which terminates in a hose connection a leading to the exhaust pipe a in a manner which will be evident.

The distributor (Z is mounted on an arm of the bracket and is provided with a shaft (Z extending at right angles to the shaft and the driving connection therefor is afforded through a bevel gear d at the lower end of a shaft (Z2 for the distributor and 'a similar bevel gear i which meshes therewith and is slipped onto the sleeve h and pinned thereon by the same driving pin h which engages the sleeve. The aligned openings tapped in the hub of the gear i and in the sleeve h are tapered slightly so that when the driving pin is threaded therein it sets up tight in the threads with the reduced end if in predetermined relation to the bottom of the reces 0. The assembly of the parts described is made with the proper meshing of the teeth of the gears i and a? to insure correct timing. all of the parts are accessible and simple and their mounting and demounting maybe readily accomplished through the bolts g for the bracket in further adapting the motor to marine purposes it will be found that the propeller shaft is ordinarily would require considerably more angularity than is present in automotive work. It is a further object of the present invention to provide means whereby such angularity will be afforded through the connection with the transmission housing a 01' the engine as shall effectively retain grease within the housing and exclude This improved connection, as will be described, is also of such character as to absorb axial thrust impressed on the shaft by the propeller is. The propeller shaft it receives power through a universal joint in from the engine shaft. A sleeve l aii'ords a bearing for the shaft 70 beyond the universal joint if and has a ea e /4.

spherical end Z which is secured Within the transmission casing a in any desired angular position by means of retaining rings m, m, of generally spherical form which are bolted onto the casing by bolts 7;. 9b viously, the angular position of the shaft]; may be adjusted as desired by the means described. ln boat structures the shatt 70" must be journalcd fixedly in position adjacent its ends. The improved ring structure serves the dual function of affording an inboard bearing for the inner end of the sleeve l thereby holding the shaft; 70 in proper alignment and also aii ording the necessary capac ity iior angulari'ty in assembling. ing strip 0 may be interposed between the spherical end Z of the sleeve and one oi the spherical rings m to retain grease and ex clude water and foreign substances. The sleeve Z may also be used as a thrust member by pinning a collar p on the shaft is in proximity to the outer end of the sleeve and interposing, if desired, an annular thrust bearing 79 between the collar and sleeve. The thrust reaction is, of course, eventually taken by the transmission casing a as is desirable.

The improvements hereinmay be modified in structural details and in the particular arrangement of parts illustrated without avoiding the spirit of the invention which is recited in more general terms in the appended claim.

W hat I claim is:

In combination with an internal combustion engine having a protruding shaft driven from the engine, a water pump mounted with its rotor aligned with the shaft, a driving sleeve connection pinned to the rotor operatively and to the shaft, a distributor mounted at one side of the shaft, and a driving gear for the distributor mounted on the said sleeve and secured to the shaft by the said pinning means.
